Background: Misreporting self-reported family history may lead to biased estimations. We used Bayesian methods to adjust for exposure misclassification. Materials and Methods: A hospital-based case-control study was used to identify breast cancer risk factors among Iranian women. Three models were jointly considered; an outcome, an exposure and a measurement model. All models were fitted using Bayesian methods, run to achieve convergence. Results: Bayesian analysis in the model without misclassification showed that the odds ratios for the relationship between breast cancer and a family history in different prior distributions were 2.98 (95% CRI: 2.41, 3.71), 2.57 (95% CRI: 1.95, 3.41) and 2.53 (95% CRI: 1.93, 3.31). In the misclassified model, adjusted odds ratios for misclassification in the different situations were 2.64 (95% CRI: 2.02, 3.47), 2.64 (95% CRI: 2.02, 3.46), 1.60 (95% CRI: 1.07, 2.38), 1.61 (95% CRI: 1.07, 2.40), 1.57 (95% CRI: 1.05, 2.35), 1.58 (95% CRI: 1.06, 2.34) and 1.57 (95% CRI: 1.06, 2.33). Conclusions: It was concluded that self-reported family history may be misclassified in different scenarios. Due to the lack of validation studies in Iran, more attention to this matter in future research is suggested, especially while obtaining results in accordance with sensitivity and specificity values.

Objectives: The purpose of this study is to evaluate the influence of depression symptom on the self-rated health status(SRHS), the outpatient health service utilization and quality of life(QOL) also the relationship depression symptom with socio-demographic and health related factors. Methods: We selected 9,550 participants without chronic diseases from a total of 18,104 in the '2009 community health survey in Gyeongnam. They were assessed by using a Korean version of the Center for Epidemiological Studies-Depression Scale(CES-D). Those with CES-D scores of 21 or greater were defined as having probable depression. Results: A probable depression were associated in bivariate analysis with gender, age, educational status, monthly household income, marital status, current smoking status, drinking habit, physical activities and body mass index. After adjustment for covariates, probable depression groups predicted a lower status in SRHS. Likewise probable depression groups predicted a higher utilization in outpatient health service. Also probable depression groups predicted a lower score in QOL. Conclusions: Probable depression influence SRHS, outpatient health service utilization and QOL even after adjusting for the socio-demographic, health related factors and chronic medical illness. Programs for prevention and management of depression will be helpful to promote health and QOL.

The purpose of this study is to investigate how the marital conflict and the conflict-coping method of self and spouse have an effect on the marital satisfaction in the early stage of marital life. The subjects of this study are the 132 couples in the area of Taegu and Pohang city. The instruments of measurement are marital conflict scale, conflict-coping method scale and Kansas marital satisfaction scale(KMSS). The data are analysed through factor analysis, Cronbach's ${\alpha}$, frequency, percentile, mean, standard deviation, paired t-test and stepwise regression analysis. The major findings of this study are as follows: Firstly, as a result of figuring out couples' marital conflict, husbands and wives are having the highest conflict in the personality factor. The difference of marital conflict between husbands and wives is shown significant in the relative factor. Secondly, as a result of figuring out couples' conflict-coping method, husbands and wives use mostly the reasonable behavior and leastly physical aggression. The difference of conflict-coping method between husbands and wives is shown significant in the verbal aggression, adjustment renunciation and physical aggression. Thirdly, as a result of figuring out how the marital conflict and the conflict-coping method of self and spouse have an effect on the marital satisfaction, the communication factor of the conflict factors, the wives' verbal aggression perceived by husbands, and the reasonable behavior of the self have much effect on the marital satisfaction in case of husbands. And the personality factor, sexual factor and role factor of the conflict factors and the husbands' verbal aggression and reasonable behavior perceived by wives have much effect on the marital satisfaction in case of wives.

Purpose: This study was conducted to develop the telecommunication guideline that was possible to make the immediate, logical decisions and to evaluate the possibility of the use by verifying it from the specialists' group. Methods: Telecommunication guideline was designed with selected six symptoms which were pain, dyspnea, nausea/vomiting, diarrhea, fever, and cough based on the results of literature. Results: This study showed that the patients understood well about the contents of the questions, examination, and education. Also, 85% of them fulfilled the guidelines of the adjustment and more of them were satisfied with the results shown to all of them compared to the previous telecommunication. And 95% of them replied that the information from the telecommunication was more useful than any other information sources related to the information of cancer and self management that were used previously. Conclusion: The telecommunication was considered to complement the weakness during the time the cancer patients spent at home after the treatments. Also, it was expected to be a role as an immediate and comprehensive method of decision making and a passage for information supply which was considered the specialty of individual patient related to an inquiry of the self management.

A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows : 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent -coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on telephone interventions were identified : guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggestion, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be understood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for extended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

This paper presents an optimal design method of a hybrid structural control system considering multi-hazard. Unlike a typical structural control system in which one system is designed for one specific type of hazard, a simultaneous optimal design method for both active and passive control systems is proposed for the mitigation of seismic and wind induced vibration responses of structures. As a numerical example, an optimal design problem is illustrated for a hybrid mass damper(HMD) and 30 viscous dampers which are installed on a 30 story building structure. In order to solve the optimization problem, a self-adaptive Harmony Search(HS) algorithm is adopted. Harmony Search algorithm is one of the meta-heuristic evolutionary methods for the global optimization, which mimics the human player's tuning process of musical instruments. A self-adaptive, dynamic parameter adjustment algorithm is also utilized for the purpose of broad search and fast convergence. The optimization results shows that the performance and effectiveness of the proposed system is superior with respect to a reference hybrid system in which the active and passive systems are independently optimized.

In this paper, we design a perceptually invisible dot pattern layout and its recognition scheme, and we apply the recognition scheme into a smart self learning aid for interactive learning aid. To increase maximum information capacity and also increase robustness to the noises, we design a ECC (error correcting code) based dot pattern with directional vector indicator. To make a smart self-learning aid, we embed the micro dot pattern (20 information bit + 15 ECC bits + 9 layout information bit) using K ink (CMYK) and extract the dot pattern using IR (infrared) LED and IR filter based camera, which is embedded in the smart pen. The reason we use K ink is that K ink is a carbon based ink in nature, and carbon is easily recognized with IR even without light. After acquiring IR camera images for the dot patterns, we perform layout adjustment using the 9 layout information bit, and extract 20 information bits from 35 data bits which is composed of 20 information bits and 15 ECC bits. To embed and extract information bits, we use topology based dot pattern recognition scheme which is robust to geometric distortion which is very usual in camera based recognition scheme. Topology based pattern recognition traces next information bit symbols using topological distance measurement from the pivot information bit. We implemented and experimented with sample patterns, and it shows that we can achieve almost 99% recognition for our embedding patterns.

Aggregation such as computing an average value of data measured in each sensor commonly occurs in many applications of sensor networks. Since sensor networks consist of low-cost nodes with limited battery power, reducing energy consumption must be considered in order to achieve a long network lifetime. Reducing the amount of messages exchanged is the most important for saving energy. Earlier work has demonstrated the effectiveness of in-network data aggregation and data filtering for minimizing the amount of messages in sensor networks. In this paper, we propose an adaptive error adjustment scheme that is simpler, more effective and efficient than previous work. The proposed scheme is based on self-adjustment in each sensor node. We show through various experiments that our scheme reduces the network traffic significantly, and performs better than existing methods.
